| Abstract: |
| In Handan Iron & Steel Company,it is necessary to connect DN1400 pipe with DN2000 pressurized gas pipe at entry of 120m 3 gas box Therefore,a new drilling technology for join of pressurized gas pipes has been developed As compared with traditional drilling technology for join of pressurized or non-pressurized gas pipes,new drilling technology has noticeable advantages of safety,environment and economical benefits,and is valuable for metallurgy industry In this paper,the principle,feasibility,execution and economical benefit of new drilling technology are introduced At the same time,a few of proposals are offered |
